> Quoted strings, by default, are treated a streams of 8 bit bytes. with use feature 'unicode_strings'; in effect, you can include UTF8 encoded characters in quoted strings.
That's not exactly how it works. Under use utf8;, quoted strings can already contain unicode characters:
#!/usr/bin/perl
use warnings;
use strict;
use feature qw{ say };
use utf8;
my $string = 'Pérl Mönx';
say length $string; # 9, not 11
See The "Unicode Bug" for details.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
